Referring indetail tothe di'erent partsg2 designates a main compartment consisting .of a front Wall`4, a` rear Wall 6, side Walls 8, anda top WalllO. v l

"The main compartment "2 is divided into a primary oven 12 and twoseconda'ryovens 14, which' latter are arranged at oppositesi'des of the `former as shown byFigs. -3^and 5. The

tvvoioutermo'st sidewalls '1'6 onfthesecondary ovens14fan'd the front and'top vWalls 18 -and of all'three' ovens are spaced inwardly from the YWalls ofthe main'compartxnent 2tol leave Kanair' space 24 and the side WallslG and the 1 Lfrontvvall '18 'are `cow'feredwith asbestos .26 1and'28, respectively, for thev purpose of retaining the heat Within the ovens," tothe end that a'. saving 'of fuel may be eected. 'Th'erear `vvallf2l of the 'ovens' is spaced vinwardly from there'ar Wall 6 of the main compart`1nent2' to leave a lue `22 `leading,upwardly to a.V Hue 23 through which the "products 'of combustion from a lire-box`25may'escape Thelue 22 is separatedfrom the 'airspace' 24; by. means of ter ormsa part of the frame f the apparatus.

Access is hadl. to the interior 'of the primary oven 12 through a rear door 40 connected by hi11ges'42to the rearfwall 6,an'd access to the interior oftheliire-box25 1is hadthrough a rear "door 44. lAs shown more clearly by Fig. 3, theire'lbox 25 is arranged beneath the primary and secondary ovens 12 and`l4, respectively, Aand is lined with lire-brick 46 for prei venting its sheet metal side and' bottom Walls 48 and 50, respectively, from burning out.

The heat and other products of combustion passing from the `fire-box 25 through the primary oven 12 and the secondary ovens 14, escape through flues 52 and 54, respectively, located inthetop Wall 2O and'communicating with a duct l5'6 leading-to the main 'flue 23. The fines 52and 54/are V equipped with dampers 58 andfO, respectively, each of which is mounted upon a shaft 62 operably mounted in bea-rings 64 secured to the top WallaQ/O. Each shaft '624 proj e'cts'through therear Wall 6 and is bent tov form ai handle 66 whereby it may be turnedV to' open and closeits respective damper. A y Y l 68 designates a dampery for controlling communication between the lire-box 25 and the lower portion of the iue 22. Said damper 68 is connected by a hinge 70 to an angle bar 72 forming a portion of the frame of the apparatus. The lower margin of the damper 68 is arranged to close against an angle bar 74 and said damper is controlled with a handle 76 extending through a slot 78 in the rear wall 6.

Each secondary oven 14 is provided with a plurality of rotary containers 80 made in skeleton form so that the heat and products of combustion from the {ire-box 25 may circulate freely through said containers. In the present instance l have shown each container consisting of a plurality of equally spaced longitudinal bars 84 and rings 86 and 88 to which said bars 84 are rigidly secured. The bars 84 are bent at angles at one end and secured to a disk provided with aI ixedly mounted and axially disposed stub shaft 92 which is journaled in a bearing 94 secured to the front wall 18 of the ovens 12 and 14.

Each stub shaft 92 is provided at one end with a fixedly mounted ratchet wheel 96 adapted to be rotated step by step by a pair of links 98 provided with a transverse pin 100 for engaging the teeth ot the respective ratchet wheel 96. The links 98 are pivotally connected at their upper ends to links 102 which are pivotally connected at their adjacent ends to a support 104 consisting oi a vertically disposed bar secured at its upper and lower ends to plates 106 lixed to the front wall 18. The outer ends ot' the links 102 are pivotally connected to a pair of vertically disposed reciproeatory bars 108 which are pivotally connected at their upper and lower ends to rocker arms 110 mounted intermediate their ends upon pivots 112 extending through the bar 104 and secured to the plates 106. The lower end of one of the bars 108 is pivotally secured to the upper end of a connecting rod 114 which is pivotally secured at its lower end to a disk 116 xedly mounted upon a shaft 118 journaled in bearings 120. The shaft 118 is driven by an electric or other suitable motor 122 through the intermediary of gears 123 and 124.

The ratchet wheels 96 are prevented from turning backwardly as the links 98 move forwardly by pawls 126 pivotally connected at their lower ends to the bar 104 and provided at their upper ends with transverse pins 128 for engagement with the teeth of the respective ratchet wheels 96. Any tendency of the connecting` rod 114 to move the lower end of the bar 108, to which it is conneeted, backwardly or forwardly, is overcome by a guide 130.

In addition to providing the mechanism above described for rotating the containers 80 step by step, I also provide means for rotating an ornamental top surmounting the main compartment 2 and in the present instance consisting of a rotary member 132 surmounted by an electric or other suitable lamp 134 and ornamental brackets 136 for attracting the attention of prospective customers. The rotary member 132 is ixedly mounted upon a shaft 138 journaled in bearings 140 and provided with a i'lxedly mounted ratchet wheel 142.

The ratchet wheel 142 is rotated step by step by means of a spring pressed pawl 144 1 pivota-lly mounted upon a lever 146 which is rockably mounted at one end upon the shaft 138. rllhe opposite end of the lever 146 is pivotally secured to one end oi' a connecting rod 148 which is pivotally secured at its opposite end to a crank 150 iixedly mounted upon the upper portion of a shaft 152 extending vertically through the ilue 22. The shaft 152 is journaled at its lower and upper ends in bearings 154 and provided at its lower portion with a iixedly mounted crank 156 having` a universal connection 157 -with the rear end of a connecting rod 158 having a universal connection 160 at its forward end with the wrist pin 117.

The rings 86, forming a` part of the rear ends of the rotary containers 80, are journaled in annular bearings 164 extending transversely through the flue 22 and iixed to the rear walls 6 and 21 as best shown by Fig. 5. Closures 166 with handles 168 are provided for closing the rear ends of the containers 80 and the rear ends of the bearings 164 so that the products of combustion passing upwardly through the secondary ovens 14 cannot escape through said bearings 164 or said closures 166. Food to be cooked may be placed directly within the containers 80, or within `grills 167, or canisters 169 which may be placed in said rotary containers 80. The open end of each canister 169 is provided with a removable closure 171 equipped with a handle 173.

Secondary compartments and 172 are arranged at opposite sides of the main compartment 2 and are provided at their rear sides with doors 174 and 176, respectively. rThe top, front, and two of the side walls olf said secondary compartments 170 and 172 consist preferably of glass to add to the attractive appearance oi the apparatus. The secondary compartments 170 and 172 are arranged above two lower compartments 178 and 180, respectively, located at opposite sides of the lire-box 25 and are provided at their rear sides with doors 182 and 184, respectively. The compartment 178 is equipped with a gas or other suitable burner 186 above which a hot plate 188is located.

The hot plate 188 is mounted upon rollers 190 arranged to traverse a track consisting of a pair of rails 192 extending through the upper portion of the iire-box 25 and the compartments 178 and 180, Fig. 3. In addition to constituting an element upon which ham` 196 in line With one of the flanges 198 extending longitudinally of each side of the hot plate 188, so that When the latter is pushed into the tire-box as above stated one of the flanges 198 Will strike the arm 196 and lift the gate 194, as shown by dotted lines F ig. 3, and thus prevent it from scraping oi'l' any food which may be cooking upon said .Y hot plate 188.

upon Which frankfurters and other articles of food may be steamed when Water is placed in the pan 200 and heated by a hame from said burner 199.

In addition to the ornamentation provided by the rotary member 132, the lamp 134 and the brackets 13G, I providethe apparatus With ornamental bars 204 and 206 which support electric or other ornamental lamps 208.

In practice the primary oven 12 serves as a receptacle in which large cuts of meat or small pigs may be barbecued by the heat and smoke arising from the lire-box 25 and passing upwardly through the primary oven 12 from which it escapes through the flue 52 into the duct 56 which conducts the heat and smoke to the main flue 28. The articles being barbecued may be placed directly upon the racks and 32 or in suitable pans or grills, not shown, placed upon said racks. The smaller cuts of meat may be barbecued in the rotary containers or the grills 167, While beans, chilli, etc., may be cooked in the canisters 169 which, like the grills 167, are removably arranged Within the containers 80. By providing the ovens 12 and 14 with dampers 58 and 60, respectively, Vthe temperature in each oven may be independently regulated to a large degree by proper manipulation of said dampers, While if va low 1 temperature is desired in all of the ovens the dampers 58 and 60 may be closed and the damper 68 may be opened to allow all of the products of combustion to pass through the flue 22 arranged between the rear Wall 21 of the ovens and the rear Wall 6.

When the rotary containers 80 are in use they are rotated step by step through the intermedi ary of the ratchet Wheels 96 and their actuating mechanism hereinbefore described, so that articles of food Within said containers .will be uniformly exposed to ,the smoke .and heat passi-ng up'vvardlyfthrough:said

containers. Y F rom the toregoing .description-it iswapparent that I` haveyprovided a bz-i'rbecue apparatus which is vvell ad-aptedwforg-the purposes intended, and While-I Shave shown one -form of said apparatus I reserve-all rights to such changes aand modilicationsas properlyfall Within'the spirit and scope 'of the invention as claimed.
